Insert image name using variable text
I'm trying to do a couple of things:
1. insert variable text field on the master page to generate image name (layer name, not actual file name)
2. Lock frame positions in the master (prevent manual positioning in pages)
Here's what I tried:
1. On master page, insert variable text "Image Name", as layer "model"


2. On master page, create a frame to hold the image, as layer "image"
3. Create some pages, drag some images into frames

4. The text renders as "No intersecting link" in both master and pages
5. Create the same variable text, directly on a page (not in the master)
6. Text renders the image filename rather than the slug/layer name (sofa 1501, bed 1601)
The other thing I'm trying to do is to prevent manual positioning of the frames so that they don't move around when I drag/position images into them
